When I used Century Link my internet went down. Seems there was a problem at my business. they told me (Twice) it was not worth there time to come and fix it. I called Cox. They came out the next day. No problem. When i could not remember my Wi-Fi password they sent Toby out to reset it and reconnect my fax line. I am not sure abut these other comments. I switched from Cox to save $10 a month with Century Link and got slower speeds and no service. Never again. I have always found their customer service helpful.
